Have these in a Magnum powered by an Alpine MRV-F405, paired with (4) RE SEX 12s powered by a Cresendo bc3500.

Despite 145+ dbs of bass, these 6x9s keep up well. I demo'd these as well as many other brands at my local audio store. For the price, I highly recommend these for a great balance between efficient screaming highs and articulate sq. The low end is significantly tighter than my stock speakers, which more punch, less low-end resonating; but my woofers take care of that anyways.

Came with *alright* 20 awg wire, flexible/tear-able gasketing material, as well as hardware.
